The clinical evolution of Lyme arthritis.
ABSTRACT To determine the clinical evolution of Lyme arthritis, 55 patients who did not receive antibiotic therapy for erythema chronicum migrans were followed longitudinally for a mean duration of 6 years. Of the 55 patients, 11 (20%) had no subsequent manifestations of Lyme disease. From 1 day to 8 weeks after disease onset, 10 of the patients (18%) began to have brief episodes of joint, periarticular, or musculoskeletal pain for as long as 6 years, but they never developed objective joint abnormalities. From 4 days to 2 years after disease onset, 28 (51%) had one episode or began to have intermittent attacks of frank arthritis, primarily in large joints; a few had polyarticular movement. The total number of these patients who continued to have recurrences decreased by 10% to 20% each year. The remaining 6 patients (11%) developed chronic synovitis later in the illness; of these, 2 (4%) had erosions, and 1 (2%), permanent joint disability. The spectrum of Lyme arthritis ranges from subjective joint pain, to intermittent attacks of arthritis, to chronic erosive disease.

ABSTRACT: The magnetic resonance (MR) imaging presentations of arthritis of the knee are important for radiologists to recognize because these disorders are often clinically unsuspected. When they are known or clinically suspected, knowledge of imaging features allows for the confirmation and characterization of the extent of disease. This article reviews the fundamental MR imaging manifestations of rheumatologic disorders of the knee and their presentation in specific arthropathies. Copyright © 2014 Elsevier Inc.

ABSTRACT: To estimate the prevalence of Lyme infection among children presenting with acute, nontraumatic hip pain in a Lyme endemic region and to investigate predictors of Lyme disease among children with suspected transient synovitis. Retrospective cross-sectional study of children with unilateral hip pain who were brought to an academic pediatric emergency department. Cases were identified by specific discharge diagnoses or radiologic imaging. Lyme infection was determined by serologic criteria, and a minimum prevalence was estimated for the entire study population; maximum estimate was determined for those who had Lyme testing. Multivariate regression was used to identify discriminating clinical findings for Lyme disease among those with nonseptic arthritis. Three hundred eighty-five children with a median age of 5.4 years were studied; 15% of children had fever ≥38.0°C and 40% had pain for less than 24 hours at evaluation. Lyme infection was identified in 5.2% (95% CI 3.2%-7.9%). A maximum estimate of Lyme disease was calculated to be 8.0% (95% CI 4.9%-12.0%). Regression analysis did not identify any practical clinical predictors of Lyme infection. Lyme infection occurred in approximately 5% of children with acute, nontraumatic hip pain who were evaluated in a pediatric emergency department in a Lyme endemic region. Based on this estimate, we do not recommend routine Lyme testing when transient synovitis is suspected; however, Lyme testing should be considered in children having laboratory studies obtained for alternative diagnoses such as septic/pyogenic arthritis and for those with an atypical clinical course for transient synovitis.
